# Bounty Engineer Delegated Agent Scope Gate

> Bounty Engineer Delegated Agent Scope Gate is a paid API for AI agents from bounty-engineer-x402-prod.onrender.com, paid per call via x402, $0.025/call, status unknown (last checked 2026-10-11).

Validates whether an autonomous agent's proposed action falls within the bounds of a pre-issued delegation mandate before allowing execution.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability bounty-engineer-delegated-agent-scope-gate-5d4eec16 -d '<json body>'
```

Example prompt: Before my agent 'agent-007' calls the 'fetch_webpage' tool targeting 'https://example.com', check whether that action is within its active mandate — the mandate allows tools ['fetch_webpage','search'], origins ['https://example.com'], up to $1.00 USD, issued today and expiring in 24 hours.

## When to prefer this

Use this endpoint when you need a lightweight, fast policy pre-check before an autonomous agent executes a sensitive tool call, payment, or external API request — especially when you want to enforce scope boundaries defined in a delegation mandate (allowed tools, origins, spend caps) before committing to execution. It is not a substitute for cryptographic signature verification or a trusted identity provider, but it is a useful first-pass gate in an agentic pipeline to catch out-of-scope actions early and generate an audit trail via SHA256 hashes.

## Known failure modes

- Missing required mandate fields (agent_id, allowed_tools, allowed_origins, issued_at, expires_at, max_spend_usd) cause validation failure
- Action destination_url not in allowed_origins returns policy_match: false
- Tool not in allowed_tools list returns policy_match: false
- Expired mandate (expires_at in the past) fails scope check
- Amount exceeding max_spend_usd triggers policy violation
- authoritative_authorization always false — endpoint explicitly warns it cannot substitute for cryptographic or identity-provider verification
- Malformed JSON body returns HTTP error
- Payment failure (insufficient USDC balance) blocks the call entirely

## How this service works

Machine-buyable infrastructure for autonomous agents: API cost routing, margin optimization, funding-rate data, webpage extraction, result verification, spend controls, retry planning, state, tender search and GitHub bounty intelligence.

## Output

Returns a JSON object indicating whether the agent's proposed action matches its delegation mandate policy (policy_match boolean), whether owner identity was verified (owner_identity_verified), whether cryptographic signatures were verified, a recommendation string (e.g. 'policy_only_allow_if_separately_authenticated'), SHA256 hashes of both the action and the mandate policy for audit purposes, a checked_at timestamp, and a prominent warning that caller-declared rules alone do not constitute authoritative authorization without separate identity verification.
